α-Amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2ZnCl2 as a bio Lewis acidic ionic liquid. Mild Lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.
Novel deep eutectic solvent (DES) using Choline Chloride (ChCl) as the hydrogen bond acceptor and triflouroacetic acid (TFA) as hydrogen bond donor (1.0:1.5 molar ratio) was prepared at room temperature and characterized by FT- IR and 1H NMR spectroscopy. Also, this novel acidic RTDES (room temperature deep eutectic solvent) was successfully used both as a […]
